Extremely bad service

My washing machine is malfunctioning which P n P assisted me by logging a call with them on Wednesday 31 March.On the 01 April I received a call from Prosper who said technician will be at my house in 3 working days. Today the 8/04/2021 is the 3rd day and I haven't received a call. I call them on *** at 10:30 and spoke to Lusindra and she said she will check the technician and revert back to me.At 13:38 I called again and there spoke to Shaiya not sure of spelling and she said the same thing. At 15:00 I spoke to Thuli who put me on hold for 7min without even telling me anything. I still have not received a call or anything from them and I am using my cell phone.
